Abstract
A lubricating device (13) for a telescopic shaft has a lubricating element and a reservoir. The lubricating device (13) is inserted into a cavity (18) of the inner profiled tube (7). The lubricating device (13) serves to lubricate the surface portions of the outer and inner profiled tubes (6, 7), which slide on one another. Thus, it is possible to achieve permanent lubrication.
